AmiBond DS series comprise of several product chemistries aimed at increased bonding within paper and board. These products may be anionic, cationic or amphoteric, based on natural “green” materials or synthetic polymers and of linear, branched or sub-branched molecular configurations. Certain products may be selected to meet the isoelectric point of the system, or for an appropriate charge density to match the system conductivity. Different products are recommended depending on the type of strength required, e.g. extensive strength such as burst or compressive strength such as ring crush.
